Background: Insomnia, the most prevalent sleep disorder, affects 10–15% of the general population. Sleep questionnaires are easily administered measure that provides a clinically relevant screening guide for sleep disorders. Sleep disorders are under-estimated in the general population studies. The Insomnia symptom questionnaire (ISQ) has 13 self-rated questions. Only questions 1, 2, 5 are used to determine the presence, frequency and the duration of sleep symptom criteria, questions 6, 13 are used to identify significant day time consequences of the sleep complaint. Approximately 2% to 5% of the population meets the diagnostic criteria for obstructive Sleep apnea (OSA) in the general population, reported to be as high as 24% in men and 9% in women. Screening tools such as the Sleep Apnea scale of Sleep Disorders Questionnaire (SA-SDQ) are gaining increasing importance because of the high prevalence of OSA in the population coupled with the high cost of PSG. Objective: To screen the presence of undiagnosed insomnia and obstructive sleep apnea in asymptomatic healthy adults Egyptians. Methods: Two thousand healthy adults Egyptians recruited from El-Kasr El-Aini hospital neurology outpatient clinics completed the Insomnia Symptom Questionnaire (ISQ) and SA-SDQ. Results:  Of the 2000 participants, 602 (30.1%) had sleep apnea, 601 (30.1%) had insomnia; female patients were more prone to experience insomnia. (P-value 0.047). Conclusion: Sleep disorders such as insomnia and sleep apnea syndrome are common problems that are under-reported in apparently healthy adult Egyptians.
